Bringing up the Bones by Lara M. Zeises

Bridget Edelstein is taking a year off before she goes to college, to try to recover from the the recent death of Benji, her longtime best friend-turned-reluctant boyfriend. Rather than accept support from her friends or family, Bridget turns to Jasper, a wonderful guy willing to nurse her broken soul–when she lets him. As she comes to terms with life without Benji, and the truth about their relationship, Bridget learns that being able to love deeply and truly is essential, even if the one you love doesn’t feel the same. More importantly, she discovers that happiness pinned to another person is only an illusion–now it’s time to find happiness on her own.
